Every welder knows the frustration of snapping a drill bit halfway through a project, especially when working with stubborn materials like stainless steel or thin sheet metal. The Walter #1 SST Stub Drill Bit (SKU: 01J001) is designed to put an end to that frustration. Built with a heavy-duty cobalt blend, this bit is specifically formulated to withstand the intense heat that kills lesser bits. If you are drilling out spot welds, installing rivets, or fabricating custom brackets, this is the bit that keeps going when others burn out. The cobalt content ensures the cutting edges stay sharp longer, saving you money on replacements and time on the job.
The secret to this bit's durability isn't just the material—it's the shape. This is a "stub" drill, meaning it is shorter and thicker than a standard drill bit. That extra stoutness gives it incredible strength. When you are leaning into a hand drill, trying to get through a piece of 1/8" plate, standard bits tend to flex and eventually snap. The Walter SST Stub Drill stays rigid, transferring all your force directly into the hole. This rigidity also makes it the perfect choice for drilling sheet metal, where longer bits can wobble and create ugly, triangular holes. With the Walter SST, you get a clean, round hole every time.
Speed matters in the shop, and the Walter 01J001 is built for it. It features a special Bronze SST surface treatment that helps the bit glide through metal with less friction. Combined with a 135-degree split point, this bit starts cutting the instant it touches the metal—no wandering, no skating, and no need to hunt for a center punch. It is designed to grab and go. Whether you are working on mild steel, aluminum, or hardened stainless, this #1 wire gauge bit delivers professional results that make your welding prep and finishing work easier and faster.
